The Pit scene was epic. In the graphic novel the Gov was just a evil screwed up ass... This Gov just seems to have mentally lost it. He was once a good guy and somewhere down he still is, but he's so screwed up that he still holds a grudge against Rick's group. I can see the little girl dying sending him over the edge again... Carol might be in that camp.
Ever since the little heart to heart Daryl and Martinez had, I've wanted to like hi characater. He seems to have some moral justice about him. The Gov is going to end up killing him in the end I predict. They might have their own little Shane/Rick moment.
I can see the next 2-3 episodes focusing on the Gov, and it would be a nice breather from the Prison. If the little girl dies, it will be some type of accident caused by Rick's group, and its going to lead to a big showdown I bet. Maybe Carl puts a bullet in her.
*Cue Epic scene from the comic that features a character that never appeared in the show*
From the Atlanta group before Hershel's farm, twins lose there mom and dad. Dale and Andrea take them in and one of the boys kills his own brother because hes f'ed up in the head... no one knows how to handle so they lock him in a van, and Carl takes care of it at night. The secret is kept between Rick and Tyrese forever.
